Below is an update to the NFS/RDMA documentation that clarifies how
to run mount.nfs. Could you please merge this for 2.6.26?

+ If you have nfs-utils version 1.1.1, use this command:
> /path/to/your/mount.nfs <IPoIB-server-name-or-address>:/<export> /mnt -i -o rdma,port=2050

To verify that the mount is using RDMA, run "cat /proc/mounts" and check the
"proto" field for the given mount.
